Description

Technical Field

[0001] This utility model applies to the field of powder collection technology and provides an integrated dust collector with external vortex and external filtration. Background Technology

[0002] A cyclone separator is a device used for separating gas-solid or liquid-solid systems. Its working principle relies on the rotational motion caused by the tangential introduction of airflow, which throws solid particles or liquid droplets with significant inertial centrifugal force against the outer wall, separating them. The main characteristics of a cyclone separator are its simple structure, high operational flexibility, high efficiency, convenient management and maintenance, and low cost. It is used to capture dust particles with a diameter of 5–10 μm or larger and is widely used in the pharmaceutical industry. It is particularly suitable for coarse dust particles, high dust concentrations, and high-temperature, high-pressure conditions. It is also often used as an internal separation device in fluidized bed reactors or as a pre-separator, making it a widely used separation device in industry.

[0003] However, due to factors such as ambient humidity and temperature, some extremely small solid particles often cannot be collected when a cyclone separator is in use. Instead, they are discharged with the flowing air. When the airflow is large, these discharged solid particles can cause a certain degree of dust pollution. Utility Model Content

Detailed Implementation

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0026] Example:

[0027] See Figure 1-4 The purpose of this utility model is to provide an integrated dust collector with external cyclone and external filtration, including an outer cylinder 1 and an inner cylinder 4. The outer cylinder 1 includes an upper cylinder 2 and a lower cylinder 3. The upper cylinder 2 is arranged around the inner cylinder 4. An inlet 5 and an external cyclone duct 6 are provided on the side wall of the upper cylinder 2. One end of the external cyclone duct 6 is connected to the inlet 5, and the other end of the external cyclone duct 6 is connected to the outer wall of the upper cylinder 2. The lower cylinder 3 is conical. Several dust collectors 7 are installed inside the inner cylinder 4. Each dust collector 7 includes a support frame 9 and a dust collector bag 8, which is arranged around the support frame 9. A high-speed airflow carrying dust particles reaches the external cyclone duct 6 through the inlet 5, and then reaches the outer cylinder 1. After reaching the outer cylinder 1, the high-speed airflow moves downward along the upper cylinder 2. After reaching the lower cylinder 3, the flow rate of the high-speed airflow slows down. At this time, the dust particles carried by the high-speed airflow separate from the high-speed airflow, and the dust particles fall towards the bottom of the lower cylinder 3. The high-speed airflow moves towards the inner cylinder 4.

[0028] Since the inner cylinder 4 is equipped with a dust collector 7, dust particles that are not separated from the high-speed airflow will be intercepted by the dust collector bag 8, while the high-speed airflow will pass through the dust collector bag 8 and be discharged.

[0029] To facilitate control of material flow out of the lower cylinder 3, a frequency converter unloader 10 is installed at the bottom of the lower cylinder 3.

[0030] To facilitate the high-speed airflow to the outside, a sealing shell 11 is installed on the top of the upper cylinder 2. The top of the inner cylinder 4 is connected to the sealing shell 11. An induced draft fan 12 is installed on the top of the sealing shell 11. An air outlet 13 is provided between the induced draft fan 12 and the inner cylinder 4, and one end of the air outlet 13 is connected to the side wall of the sealing shell 11. The induced draft fan 12 provides power for the airflow. The high-speed airflow, filtered by the dust collector bag 8, is discharged through the air outlet 13.

[0031] When dust particles accumulate to a certain amount on the dust collector bag 8, they will obstruct the flow of high-speed airflow. To avoid this problem, a pulse jet cleaner 14 is installed on the side wall of the upper cylinder 2, and the dust collector 7 is connected to the pulse jet cleaner 14 by a pipe. After a period of use, the pulse jet cleaner 14 will release a short burst of high-pressure, high-speed air towards the dust collector 7. As the high-speed air moves along the dust collector 7, the dust collector bag 8 will inflate with the movement of the high-speed air, causing the dust particles accumulated on the dust collector bag 8 to fall off, thus restoring the interception capacity of the dust collector 7.

[0032] To facilitate the installation of the pulse jet 14, a support frame is installed on the side wall of the upper cylinder 2. The support frame includes a support plate 15 and a support arm 16. The pulse jet 14 is installed on the top of the support plate 15. One end of the support arm 16 is connected to the side wall of the upper cylinder 2, the side wall of the support arm 16 is connected to the bottom of the support plate 15, and one end of the support plate 15 is connected to the side wall of the upper cylinder 2.

[0033] Most existing support frames 9 are of fixed length, which makes it difficult to match the length of the dust collector 7 with the inner cylinder 4, resulting in it being either too long or too short. Therefore, the length of the dust collector 7 needs to be redesigned. If the length of the inner cylinder 4 changes, the length of the dust collector 7 also needs to be rematched to the inner cylinder 4. Figure 4-9 As shown, to facilitate adjustment of the length of the dust collector cylinder 7, the support frame 9 includes a fixed ring platform 17 and several hollow frames 18. The bottom of the fixed ring platform 17 is connected to the top of the hollow frames 18, and adjacent hollow frames 18 are connected end to end. During use, a fixing plate is installed in the inner cylinder 4, with fixing holes corresponding to the dust collector cylinder 7. The dust collector cylinder 7 is vertically positioned in the fixing holes. To facilitate fixing the dust collector cylinder 7, the support frame 9 includes a fixed ring platform 17, which engages with the fixing holes. The length of the hollow frames 18 is fixed, so the required number can be selected for assembly according to design needs.

[0034] To facilitate the connection of the two ends of the hollow frame 18, the hollow frame 18 includes an upper end 19 and a lower end 20. The upper end 19 is provided with several locking platforms 21, and the lower end 20 is provided with locking slots 24 that mate with the locking platforms 21. Each locking platform 21 includes a protrusion 22 and a clearance area 23. The locking slot 24 includes a locking interface 25 and a positioning part 26. The positioning part 26 covers a portion of the locking interface 25, and the clearance area 23 mates with the positioning part 26. In use, the locking platforms 21 and the locking slots 24 are aligned, and then the locking platforms 21 are inserted into the locking slots 24. Subsequently, the hollow frame 18 is rotated. At this time, the protrusion 22 of the locking platform 21 passes through the locking interface 25 and enters the locking slot 24, and the clearance area 23 and the positioning part 26 are inserted together.

[0035] The above design connects adjacent hollow frames 18 via a plug-in method, but this method carries the risk of detachment. To address this, the lower end 20 has several first grooves 27 on its side wall, and the upper end 19 has several second grooves 28 on its side wall. The first grooves 27 and second grooves 28 are fitted together. A retaining plate 29 is hinged within the first groove 27, and a boss 30 is provided at the bottom of the retaining plate 29. A third groove 31 is provided at the bottom of the second grooves 28, and the boss 30 is fitted together with the third groove 31. After the adjacent hollow frames 18 are fixed, the first groove 27 of the upper end 19 and the second groove 28 of the lower end 20 are aligned. At this point, the retaining plate 29 within the first groove 27 will rotate towards the second groove 28, and finally, the boss 30 will insert into the third groove 31. Once the boss 30 is inserted into the third groove 31, the adjacent hollow frames 18 will be unable to rotate, thus further securing them and reducing the probability of the hollow frames 18 detaching.

[0036] Preferably, both the boss 30 and the third groove 31 are provided with magnets, and the boss 30 and the third groove 31 attract each other.

[0037] To facilitate opening the card plate 29, a protrusion is provided on the side of the card plate 29 away from the boss 30.

[0038] In summary, the advantages of this solution are as follows: First, the separation of flowing air and dust materials is achieved through the cooperation of the upper cylinder 2 and the lower cylinder 3. Subsequently, the dust collector 7 intercepts the extremely small dust particles carried in the flowing air, ensuring the purity of the discharged air and avoiding dust pollution problems. Second, it integrates the functions of a dust collector and a cyclone collector, and has a small overall footprint.

[0039] Of course, there may be other embodiments of this utility model. Without departing from the spirit and essence of this utility model, those skilled in the art can make various corresponding changes and modifications based on this utility model, but these corresponding changes and modifications should all fall within the protection scope of the appended claims of this utility model.
